Doepfer A-140

ADSR Envelope Generator

The module A-140 is a envelope generator and since it delivers control voltages, belongs to the modulation-modules. As soon as the ADSR is triggered at gate-input, it generates an adjustable control signal called the envelope. This envelope is present on its outputs in normal and inverted S-form and can be used e.g. for modulation of VCO, VCF and VCA modules as well as for transient and decay oscillations of other modules. The S-form of the envelope is unambiguously defined by four parameters, attack, decay, sustain and release. The ADSR is triggered with a gate-signal at gate-input and provides the possibility of a retrigger-Function, i.e. the envelope will be restarted every time a trigger signal is present at the retrigger-socket while the gate is active.

In connection with the comparator-module A-167 a free run "ADSR-LFO" can be realised.

Simple and effective
25.03.2015
There's a bit of snobbery in the forums for most Doepfer modules however what you get is something that isn't glamorous, won't do amazing tricks that you didnt expect, but something that is logical, easy to use and most importantly easy to control.The Doepfer A-140 ADSR is a great example of simple, effective design and it gets used regularly to add control to some of the wilder sounds designed. Lets face it, it's not the most attractive of modules and when you line up set of the Doepfer modules in a unit there is a higher risk of falling asleep spontaneously but they are workhorses and worth the money!

Great little ADSR
LiamJ, 10.02.2015
This is an integral part of your modular setup, I suggest buying 1 for each oscillator you have in your setup too, adds a bit of life to your patches to vary the sound of your boring old oscillator.

Nice ADSR

This is a nice ADSR with a very useful range from milliseconds to minutes and an inverse output too at a great price.
